Abstract: A technique is configured to provide various data protection schemes, such as replication and erasure coding, for data blocks of volumes served by storage nodes of a cluster configured to perform deduplication of the data blocks. Additionally, the technique is configured to ensure that each deduplicated data block complies with data redundancy guarantees of the data protection schemes, while improving storage space of the storage nodes. In order to satisfy the data integrity guarantees while improving available storage space, the storage nodes perform periodic garbage collection for data blocks to optimize storage in accordance with currently applicable data protection schemes

Abstract: A technique is configured to provide data protection, such as replication and erasure coding, of content driven distribution of data blocks served by storage nodes of a cluster. When providing data protection in the form of replication (redundancy), a slice service of the storage node generates one or more copies or replicas of a data block for storage on the cluster. Each replicated data block is illustratively organized within a bin that is maintained by block services of the nodes for storage on storage devices. When providing data protection in the form of erasure coding, the block services may select data blocks to be erasure coded. A set of data blocks for erasure coding may then be grouped together to form a write group. According to the technique, EC group membership is guided by varying bin groups so the data is resilient against failure. Slice services of the storage nodes assign data blocks of different bins and replicas to a write group.
